如何为该映射文档编写单元测试查询？

Question

This is the mapping document

我被要求写一个“单元测试”来测试这个映射文件。我查询正确吗？

我有多个选择语句，但不确定执行是否正确。对于映射文档中的每一行，我都有一条select语句。

我正确地执行了这个“单元测试”吗？

SELECT agreement_id
FROM event JOIN agreement_event
ON event.event_id = agreement_event.event_id
WHERE event_activity_type_cd = 'update_address_phone_number'

ON event.event_id = agreement_event.event_id
